Not really Lynn, I've messed up and missaligned mine and the key is fine, the pulley groove is what takes the damage. The 3-4 people out of about 50 that had this problem from the factory was that the woodruff key was crack and this was evident before anyone put the ASP pulley on so no engine damage occurred to my knowledge. I do know of someone personally that this happened to (actually 2 in South O.C.) and he tried to fix it himself and ended up pushing the broken half of the key back into the engine. This of course required removing the engine to fetch it and install a new one, his costs about $1,100. If you do see something abnormal with the key then put the factory pulley back in and forget about it.
